what do an electron and a neutron have in common? each particle has a mass of 1 amu. each particle exists inside an atom. each particle has an electrical charge. each particle is located in the nucleus.
Answer
Brief Explanations:
Electrons and neutrons are sub - atomic particles. Electrons have negligible mass compared to 1 amu, neutrons have a mass of about 1 amu. Electrons are negatively charged, neutrons are neutral. Electrons are outside the nucleus, neutrons are in the nucleus. But both are part of an atom's structure.
Answer:
Each particle exists inside an atom.
